Abstract

The invention discloses a coil pipe fan structure which comprises an air blower, a fan box and a heat exchanger. The air blower comprises a volute, an air wheel and a motor, the air wheel is mounted in a first cavity of the volute, and the volute is provided with a first air inlet and a first air outlet. An output shaft of the motor stretches into the first cavity to be connected with the air wheel in a mounted manner, the fan box is provided with a second cavity, a second air inlet is formed in one side of the fan box, and a second air outlet is formed in the other side of the fan box. The heat exchanger is mounted in the second cavity and located between the second air inlet and the second air outlet, a volute tongue part of the first air outlet of the volute is connected with an inclined plate, the higher end of the inclined plate is connected with a volute tongue of the volute air outlet, and the lower end of the inclined plate obliquely extends downwards in the direction close to the heat exchanger. A static pressure reset device is arranged on the first air outlet of the volute, on the basis of the static pressure reset device, volute parameter setting meets the following condition that 1.65>=2*b2 / D2>=1.45, the operating efficiency of the motor and the operating efficiency of the fan can be effectively improved, and noise of the fan can be reduced.
